GSM covers making phone calls, sending SMS text messages, and access to Internet via GPRS. A SIM (Subscriber Identity Module) card is given along the contract with an operator, and the customer inserts the card in the phone to authorize it. The card is plastic (approximately 15mm*23mm*1mm) with several gold contacts on, and it determines the mobile phone 'number' and what network the phone is on.

The Neo1973 phone should work with any operator that has a GSM network (see Neo1973 compatible cellphone providers); it is quad-band and thus supports every frequency (850, 900, 1800, and 1900 MHz). Thus it will work in most countries, with the exception of some of the US and some other parts of the world that completely lack GSM coverage.
